The outer or face wall 19 of each of the individual strip sections has con? nccted therewith inwardly diver-"eat side walls or flanges 2l.'which dovetail into the channel ali'orded by the inwardly divergent walls 17 so that after the individual strip section has been driven or slid into place in the channel provided therefor it will be held rigidly in lace. If it is desired to secure an exceptiona ly tight fit the 'side walls or flanges can be given a divergence sutlicicnt to require a slight contraction in order to drive them to place within the channels, although ordinarily a reasonably tight fit will be sutlicicnt. The continuous sheathing thus formed is applied to the lower wall 22 of the car, below the sash rest, by securing the continuous channel plate or strip 14 by means of screws 23 which are entered through the inner walls of the channel portions so that, when the individual slats or strips are inserted within the channels the screw heads will be entirely concealed and a smooth finish provided,unbroken save only by the parzillel seams or joints such as usually appear in the sheathin of a wooden car. In order to provide dead air spaces, a plurality of wooden plugs 24 are driven into the open ends of the channel and rib portions of the sheathing, so that a plurality of dead air spaces are afforded which serve to insulate the carmore thoroughly against heat'and cold.

The upper edge of the continuous sheathing, formed as above specified, is covered and protected by a continuous sash rest 11, whic comprises a sloping body portion 26, which, at its lower edge, merges into an outwardly rounded portion 27 the lower edge 28 of which isrercrsely bent or turned to afford a U shape channel which receives the lower edge 29 of a connecting strip 30, which is screwed or otherwise rigidly secured to the frame of thecar 31 immediately below the window openings. The lower edge 29 is off-set sutticiently to provide for the en 'agement of the reversely turned or hooke edge 28 of the sash rest, which latter is secured only near its upper edge by means of screws 32 which are ontered into the top of the frame 31 which comprises the window sill. The bent or turned lower edge of the sash rest closely abuts again the outer face of the contimr ous sheathimr, near the upper edge thereof,

and serves to'provide a very attractive finish for the unprr ilge of the continuous sheathmg and a: the same trme thoroughly protects the sheathing at this point against dis placement andagatnst the adnncsion ot dirt or moisture.

The slat formationot' sheathing which I is intended to be secured to the car all in individual sections is prefera ly applit'd to those portions of the ar which are of such limited extent or irregular shapg as to 'reir der the application of continuous strips difficult: or impossible. The strip sections of the continuous sheathing, it will be understood must be drivcnno position from the and, within the channels, and under certain conditions it is ditlicult or impossible to suc cessfully do this. for which reason the indi-' vidual slat sheathing is provided. The latter comprises a plurality of strips or sections 33, each of which is in the form of a chan- -neled strip of metal bent or died to pan Ede an outer or face wall 34, which is p ovided, along one et ge, with a diagonally inwardly extending side wall 35 terminating in an attaching flange 36 parallel with the face of the strip. The face plate or portion 34 is provided, along its other edge, with dia onally outwardly extending side wall 37 0? less depth than the companion side. wall and terminating in an inwardly extending flange 38 which forms an elbow or angle adapted to dovetail into the angle afforded by the attaching side wall of the n xt adjacent slat or seation. The slats the formed are laid edge to edge, and each is secured along one edge by means of bolts or screws 39 which are entered through the inwardly extending attaching flange as. The opposite edge of the strip thus secured is held in place by thecngagement of the unattached wall 37 with the abutting attached wall of the next adjacent section, with which it dovetails, so that the strips thus formed and laid will be held in place against displacement. It is obvious that the individual slats, thus formed, can be fitted into any corner or small area which it; is desired to sheath, since they do not need to be driven cndwise to place and can be more readily.

formed. cut and fitted than the continuous sections of sheathing. The upper ends of the slats or sections thus formed are preferablycntcrcd into a groove -10 in the name board 13 of the car. which, as shown, is formed of wood. although it might be otherwise formed. The ends of the slats or sections above the windows rest upon a metallic lintcl plate 42 of'channel formation. By combining the two styles of sheathing thus formed and secured. the. sheathing operation will be greatly facilitated for the reason that he continuous sheathing can be I very quickly applied to wide or extended areas like that afforded by the lower car all. since the continuous channeled plate can be laid against the intended surface and Hit? attached thereto by inserting the required number of screws or rivets into the channels. Thereafter the individual strips or sections required to complete the continuous sheathing can be driven to place and the operation is complete. The. continuous sheathing atl'ords a maximum of strength by reason of its corrugated unbroken formation so that, where it can be thus rigidly secured it is desirable to use it. At the same time. bv fini hing the up ier portions of the wall with the slat or individual form of sheathing no ditliculty will be experienced in applying the sheathing to restricted areas or irregular surfaces, to which it would be ditlicult. if not impossible, to apply the other style of sheathin The continuous sash rest forms a ledge from end to end of the car. which serves to top oil' the upper edge of the lower or continuous section of sheathing and at the same time atiords a rest for the lower ends for the upper slat sections of sheathin The shcuthing is highly superior to a sheathing of flat metallic plates in that it is much stronger by reason of its corrugated or channeled formation. is much more attmctive in appearance and is more impervious to changes in temperature by reason of the provision of the dead air spaces.
